The well known SBD source has one major flaw. It is not stereo. The same channel is spread over both channels using a splitter technique. The channel that should contain Keith, half of Jerry, Billy, and possibly some of Phil, is missing; Keith is minimally audible. This is the only SBD source available.
The Wagner recording is very nice quality. Once aligned with the SBD the whole sound spectrum can be heard. Bobby is no longer drowning out the others and Jerry's sound is much richer and fuller. The biggest difference is that Keith can be heard.
The SBD and the Wagner recording have many cuts primarily between songs. I used the FOB to fill in most of these gaps where possible. I went into this project with the intension of constructing a 2-source Matrix between the SBD and Wagner sources. I found the cuts and fades between tracks very annoying so I added the FOB to fill in between the cuts only. I did not align the FOB with the other two sources through the songs because I felt it did not add to the overall quality of the Matrix. I also fixed drop outs, static, level fluctuations and clicks throughout.
The results are a big improvement for this show. This is the most complete version of this concert since all 3 recordings have different cuts and it is now seamless with the exception of the break between sets. Everybody in the band can be heard clearly and evenly.
